N <br />Slope and Final Contours <br />(Construction Materials Rule 3.1.5 (1), (3) and 6.3.4 (1b)) <br />As previously mentioned, a considerable portion of the south facing dominant <br />slope is underpinned by bedrock(some exposed and some not) and has been <br />stable for 40 or more years. Further the current slopes are represented in <br />the in the natural surrounding terrain. There is a 0.25 acre area that we <br />highly recommend to be left in place and not reduced in slope (Appendix E, <br />Map E5). The mentioned steep slopes have not been disturbed since the <br />1970s. This will be discussed further in the technical revision summary <br />section. <br />The rest of the site should vary from roughly level to a slope no greater than <br />2/1 which roughly represents the steeper slopes on the north side of the hill <br />(undisturbed area, Appendix E, Map E5). Keep in mind that the target is 3/1 <br />as that is stable, easier to vegetate, and aids in controlling erosion. Outside <br />of the previously mentioned 0.25 acre area that ranges from 1/1 to 1.6/1, <br />the mined slopes range from 3.1/1 to 3.4/1. <br />While it would be possible to meet the proposed 1995 final contours it would <br />entail removal of a most of the hili and available product (Appendix E, Map <br />4). Thus it is highly unlikely given the current rate of product removal that <br />the proposed 1995 contours would be realized for a considerable time. <br />We have not provided a specifically designed set of contours as the future <br />product removal from the pit is uncertain. We do suggest that the operator <br />keep in mind the surrounding land form and the designated usage at final <br />abandonment. As such the land will be used to support the Vista Del Sol <br />ranching operation (e.g. storage of ranching supplies, staging location). <br />Currently the pit is grazed by both wildlife and livestock. <br />37 1 Page <br />FOR: VC3WL11 GRAV k 1.
